Despite what many would probably remember for years as the most shocking month for Solana, the ecosystem has withstood the shock and moved forward, haven’t lost either developers or their dApps. As this transpires, Everstake offers its own contribution to the further progress of Solana with extrnode, a major project aiming at fixing the RPC layer in Web3 ecosystems, especially Solana. The project's first outing is the extrnode open-source load balancer, a solution that redirects requests from faulty PRC nodes to operational ones. extrnode’s creators opted to have it beta-tested by the community before releasing production-suitable versions and now only recommend using the solution for testing purposes. Any feedback is welcome on the official with the source code available and a ready-made Docker image . , Discord here here RPC is the backbone of Web3 While the blockchain layer is sufficiently decentralized, this can’t be said about the RPC layer despite its crucial importance for the proper operation of the crypto ecosystem. When your application, say, a wallet, communicates with the blockchain, it actually sends your commands in the form of code to an RPC node designated by the developer so that the blockchain can record and verify your actions. No communication is possible if something goes wrong with the RPC node, and your application becomes futile. This situation is hardly imaginary. This very November, the hosting provider Hertzner killed all Solana nodes on its services, paralyzing dozens of dApps and cutting off 22% of the network’s nodes in a single blow. Even though this is not enough to strangle an entire ecosystem, it is still a valuable lesson about the fundamental vulnerability of the RPC layer that can go south on a whim of a hosting provider or regulator. An obvious solution to this problem is to run your own RPC nodes and never depend on a third party. Still, it’s an expensive way out, with bills starting at around $1,000 per month. This leaves most dApp developers in the hands of major providers like the aforementioned Hertzner or even bigger fish like Amazon Web Services or Google Cloud. None of this is a secret, so many dApp developers find a way to bypass this bottleneck with scripts, modules, or just automatic switching to an alternate RPC endpoint in case of a failure. This, however, is not a remedy, as the developer would be forced back to square one if the alternate node goes down. And that’s where extrnode comes in. extrnode’s open-source load balancer in a nutshell Right now, there are several options that developers face when it comes to ensuring steady operation on the RPC layer. They either have to pay for a decentralized balancer in project tokens whose price always varies or have to rely on third parties with centralized balancers, which is risky. Finally, as we pointed out earlier, they may launch their own balancer, but it is quite costly as it requires a dedicated team of DevOps and working agreements with numerous validators. With extrnode, there is a fourth option on the table. The distributes requests among several public RPC nodes forming a cluster and automatically reroutes all requests should the designated node fail for whatever reason. In practice, it means that no matter what happens, a dApp will stay operational as long as at least one RPC node is active. Notably, it is free to use and requires only running it on Docker. A developer can then configure it as they please. open-source load balancer This, however, is just the beginning, as the current iteration of extrnode is subject to public testing and is not recommended for production use. Still, it is quite suitable for testing applications on the mainnet. In a short while, will release a free-to-use version of extrnode that would comply with the safety and reliability requirements of a typical dApp and use Everstake’s battle-tested infrastructure. It will be followed by a premium version for solutions requiring higher degrees of security, in which only the validators with the highest uptime will participate. Everstake While the solution currently focuses on Solana, it will be scaled up to other prominent PoS blockchains. For now, however, everyone is welcome to try the open-source load balancer so that we can boost the decentralization of the RPC layer sooner.

Solana Goes Forth with extrnode’s Open-Source Load Balancer

EVER holders will be able to enjoy unique benefits such as earning up to 20 percent annualized yield. Everscale (formerly Free TON) presents a for those who love to seize an opportunity. This limited-time offer provides EVER holders unique benefits. Designed to enable participants to receive passive income, individuals can send tokens to a special smart contract called a Depool, where they will help in validating transactions on the blockchain. Boosted Staking program What is a DePool? The Depool smart contract has passed what’s called formal verification, ensuring it is safe to allocate funds to it while keeping your own control over decisions, meaning, it’s your money. Put it in or take it out at your discretion. What is a DeBot? The Debot is a decentralized interface for communication with the Depool smart contract, offering a convenient and easy-to-use experience. Tell me more! Why, certainly! Ever Surf’s Boosted Staking program was conceived to support independent validators and decentralization. Staking has previously been regarded as an intimidating process, whether the user interface is not intuitive or the users are required to have significant token balances in order to participate. The Ever Surf browser and wallet resolves the first issues by giving users the ability to interact with the smart contract and successfully stake their tokens by running a simple chat-like interface within the browser. This interface is called the DeBot. Further lowering the entry barrier, the boosted staking program allows users to stake as little as 100 tokens to participate while the duration of the lock period is also up to the user. From 6, 12, 18, and 24 months, stakers can take advantage of varying benefits with the additional APY reaching as high as 15%. The rewards are distributed after each validation cycle, with the withdrawal process from the Depool taking up to 54 hours. Everscale Network is proud to be lowering the entry barrier and welcome new users into the staking process to experience how easy it is to earn rewards. Through this initiative, the team is encouraging the users to participate, increase the liquidity and welcome more projects in the near future. Great, how do I start? To participate in the Boosted Staking Program, please install the (if you don’t already have one) and activate your new wallet. , , , or any other exchange of your liking where EVER is listed.

Boosted Staking Debot Depending on the number of tokens you’d like to stake (100-999, 1,000-9,999, 10K-100K, 100K+) and the duration of time you’re willing to lock your tokens in (6, 12, 18, and 24 months) an additional APY will be award of up to 15% will be added to your account. Note: Traditional staking gives the user a basic 5% APY. Thus the total APY can reach up to 20%. The rewards are paid after each validation cycle with the withdrawal procedure from a DePool that may take up to 54 hours.

Introducing React Axiom November 16, 2016 edits reflect API changes since the original publishing of this article. At some point in a React application, describing state changes for application data becomes difficult at individual component levels and calls for a clean abstraction between business logic and presentational components. Redux is certainly an option at this point, but suppose the are unfavorable? tradeoffs that Redux provides is a lightweight (~12kb) way to use models with the React component tree. A basic React Axiom model looks like the following: React Axiom class ListItemModel extends ReactAxiom.Model { static defaultState() {return {id: null,description: '',completed: false};} } stores the argument object in and automatically creates getter and setter functions: , , for the property, , , for the property, and , , for the property (note: this is different due to the completed property being a boolean). Defining a method of the same name on the class overwrites the getter or setter: Model this.state getId setId hasId id getDescription setDescription hasDescription description isCompleted setCompleted hasCompleted completed class ListItemModel extends ReactAxiom.Model { static defaultState() {return {id: null,description: '',completed: false};} getDescription() {return this.state.description.toLowerCase();} } When a React Axiom model is passed into a component, the component listens to state changes within the model and updates itself. The following is an example of a React component using a model passed as below: listItem class ListItemComponent extends React.Component { render() {const { listItem } = this.props;return (<li>{listItem.getDescription()}{listItem.isCompleted() ? null : this.renderButton()}</li>);} renderButton() {const { listItem } = this.props;return (<button onClick={() => listItem.setCompleted(true)}>complete</button>);} } Notice how the component calls on the model to update state. To put everything together: setCompleted listItem const listItem = new ListItemModel({id: '1',description: 'Teach mom how to use Slack'}); const ListItemSubscriber = ReactAxiom.subscribe(ListItemComponent); ReactDOM.render(<ListItemSubscriber listItem={listItem} />,document.getElementById('app')); The higher order function wraps the and returns a new component. The component will then subscribe to the model and update itself if state changes. In the specific above example, clicking on the complete button will cause the button to disappear. subscribe ListItemComponent ListItemSubscriber ListItemSubscriber listItem Getting Complex with References State changes in React Axiom models occur through mutations. As a result, this design allows references to other objects, arrays, and models to operate fairly well in state. The following example adds a field to and some additional logic to complete a list item. dependencies ListItemModel class ListItemComponent extends ReactAxiom.Model { static defaultState() {return {id: null,description: '',completed: false,dependencies: [],};} complete() {this.getDependencies().forEach(dependency => {dependency.complete();}); this.setCompleted(true); } } To recursively render list items, the component can render the component for each dependency: ListItemComponent ListItemSubscriber class ListItemComponent extends React.Component { render() {const { listItem } = this.props;return (<li>{listItem.getDescription()}{listItem.isCompleted() ? null : this.renderButton()}<ul>{this.renderDependencies()}</ul></li>);} renderButton() {const { listItem } = this.props;return (<button onClick={() => listItem.complete()}>complete</button>);} renderDependencies() {const { listItem } = this.props;return listItem.getDependencies().map(dependency => (<ListItemSubscriber listItem={dependency} />));} } const ListItemSubscriber = ReactAxiom.subscribe(ListItemComponent); Now, clicking on a complete button will mutate that model’s state value and all of its dependencies’ state value. In addition, any component that subscribed to any of the mutated list items will update and render the correct state. completed completed Use with Server Rendering One particular drawback with React Axiom is that the data store requires model names to be passed as part of the transferrable data. This is fine for server-to-client data transfer, however it is less flexible in terms of snapshotting and persisting state to a local storage should the model names change in any way. The following is an example of serializing and parsing models and model data with the React Axiom : Store const listItem1 = new ListItemModel({id: '1',description: 'Teach mom how to use Slack'}); const listItem2 = new ListItemModel({id: '2',description: 'Meditate',dependencies: [listItem1]}); ReactAxiom.Store.setModelRefs([ListItemModel]); const serverStore = new ReactAxiom.Store({title: 'Things to do',createdAt: Date.now(),listItems: [listItem1, listItem2]}); const json = serverStore.stringify(); // Transfer the data to the client// to hydrate the client store, and// reinitialize the application. ReactAxiom.Store.setModelRefs([ListItemModel]); const clientStore = new ReactAxiom.Store(); clientStore.parse(json); Notice how contains a reference to on the server store. By passing in classes to initialize the client store, it is able to rebuild this reference from the provided JSON string. In other words, on . listItem2 listItem1 listItem2.getDependences()[0] === listItem1 clientStore When to Use Models Like any design, there are tradeoffs. Redux, for example, requires plain objects to describe changes in the system and pure functions to describe the logic for handling those changes (what a lot of developers refer to as “boilerplate”) but gains a more flexible data store. React Axiom requires models to describe the changes in the system describe the logic for handling those changes, but gains the following advantages: and Organizing and stubbing business logic becomes easier. Interfaces between views, models, and data become more flexible. Writing semantic and transparent code becomes easier. For someone new to the React ecosystem, React Axiom might make a little bit more sense than Redux, but like any framework or design that is opinionated, only use it if solves a particular problem or fits the situation. What is Next? React Axiom is still in its infancy stage. I welcome any help to make this design paradigm a robust solution for large scale applications for the JavaScript community.
